Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 1. #41⋊ΓL(1,𝔽8) | C2 | semidirect |
| 2. C7×H(5,𝔽2) | C3 | semidirect |
| 3. C7⋊SL(2,𝔽3) | C22 | semidirect |
| 18. H(5,𝔽2) | ΓL(1,𝔽8) | semidirect |
| 38. C7 | #994 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
